on one's last legs, to be

To be extremely tired or about to collapse; near the end. Despite the implication, this term never meant that legs were in any way serial—that is, beginning with the first and ending with the last. Rather, it uses last meaning “near the end” (of one’s energy or life). The expression was already used in the sixteenth century; it appears in the play The Old Law (1599) by Thomas Middleton and Philip Massinger: “My husband goes upon his last hour now—on his last legs, I am sure.” In John Ray’s Proverbs (1678) the term is defined as meaning “bankrupt,” and since then it has been transferred to anything nearing its end or about to fail, as in, “This cliché may be on its last legs.”See also: last, on
